Mammy Representations In The 21st Century, Ayondela Mcdole

Theses - ALL

This thesis examines the signification of the mammy stereotype in the 21st century. The performances of Martin Lawrence, Tyler Perry and Eddie Murphy’s as mammies in drag are the selected texts for the project. By presenting the many mammy representations over the past 150 years, I outline the ways in which the mammy stereotype dehumanizes black women and hinders the Pan African agenda. Through the commodification of the mammy stereotype it has been de-historicized and thus separated from its beginnings as a part of the white supremacist imagination. Discourse analysis is used to analyze its meaning and signification while black …

Including Pork In The Mediterranean Diet For An Australian Population: Protocol For Arandomised Controlled Trial Assessing Cardiovascular Risk And Cognitive Function, Alexandra T. Wade, Courtney R. Davis, Kathryn A. Dyer, Jonathan M. Hodgson, Richard Woodman, Hannah A. Keage, Karen J. Murphy

Research outputs 2014 to 2021

Background

The Mediterranean diet is characterised by the high consumption of extra virgin olive oil, fruits, vegetables, grains, legumes and nuts; moderate consumption of fish, poultry, eggs and dairy; and low consumption of red meat and sweets. Cross sectional, longitudinal and intervention studies indicate that a Mediterranean diet may be effective for the prevention of cardiovascular disease and dementia. However, previous research suggests that an Australian population may find red meat restrictions difficult, which could affect long term sustainability of the diet.

Methods

This paper outlines the protocol for a randomised controlled trial that will assess the cardiovascular and cognitive …

Associative Pattern Recognition For Biological Regulation Data, Yiou Xiao

Dissertations - ALL

In the last decade, bioinformatics data has been accumulated at an unprecedented rate, thanks to the advancement in sequencing technologies. Such rapid development poses both challenges and promising research topics. In this dissertation, we propose a series of associative pattern recognition algorithms in biological regulation studies. In particular, we emphasize efficiently recognizing associative patterns between genes, transcription factors, histone modifications and functional labels using heterogeneous data sources (numeric, sequences, time series data and textual labels).

In protein-DNA associative pattern recognition, we introduce an efficient algorithm for affinity test by searching for over-represented DNA sequences using a hash function and modulo …

Collaboration And Conflict In Transnationally-Dispersed Zimbabwean Families, William John Suk

Dissertations - ALL

Approximately one quarter of Zimbabwean adults left their country of birth during the past twenty years. These sojourners are increasingly dispersed as tightening immigration regimes in preferred destinations and fluctuating global opportunities lead them to places with fewer historical links to Zimbabwe. This dispersive process fractures many families between multiple international locations. Nevertheless, the idea of family remains centrally important to diasporans, who work with relatives around the world to care for children and elders, to acquire important documents like passports, and to prepare for an eventual return home. Following from performative and relational theorizations of kinship, this dissertation argues …

Limits Of Liberation: Youth And Politics In Brazil's Landless Rural Workers' Movement, Melinda Gurr

Dissertations - ALL

This thesis examines the forces that strengthen and weaken young people’s involvement in Brazil’s Landless Rural Workers’ Movement, the MST, during the twilight of the PT years, 2012-2014. The MST responds to displacement, environmental devastation, and capital- intensive development by fighting for land reform and socialist transformation. Although the MST’s politics of redistribution have attracted significant attention from activists and academics worldwide, little ethnographic attention had yet been paid to the experiences and subjectivities of rural youth affiliated with the movement. By attending to structural conditions, dynamics of family, sexuality, and gender, and political socialization in three regions of Brazil, …

Are Fireworms Venomous? Evidence For The Convergent Evolution Of Toxin Homologs In Three Species Of Fireworms (Annelida, Amphinomidae), Aida Verdes, Danny Simpson, Mandë Holford

Publications and Research

Amphinomids, more commonly known as fireworms, are a basal lineage of marine annelids characterized by the presence of defensive dorsal calcareous chaetae, which break off upon contact. It has long been hypothesized that amphinomids are venomous and use the chaetae to inject a toxic substance. However, studies investigating fireworm venom from a morphological or molecular perspective are scarce and no venom gland has been identified to date, nor any toxin characterized at the molecular level. To investigate this question, we analyzed the transcriptomes of three species of fireworms— Eurythoe complanata, Hermodice carunculata, andParamphinome jeffreysii—following a venomics approach to identify putative …

The Great Lakes Entomologist

(excerpt)

I was eager to review this publication. When I was a young person, first starting the pursuit of Lepidoptera, any literature that increased my knowledge was as valuable as the specimens I collected. Checklists were especially welcome. A primary purpose for the formation of The Ohio Lepidopterists society was to record the occurrence of Lepidoptera in Ohio. My ardent commitment to document Ohio's fauna over the past 20 years gives me insight into the work necessary to create and produce a publication of this type.

Notes On The Life Histories Of Chlosyne (Lepidoptera: Nymphalidae) And Agrypon (Hymenoptera: Ichneumonidae), Andrew H. Williams

Ambrosia trifida is reported for the first time as a larval food plant of Chlosyne nycteis. Chlosyne nycteis and C. harrisii are reported as hosts of Agrypon prismaticum and A. alpinum, respectively; the first report of wasps in Agrypon parasitizing species in Nymphalidae.

First Report Of The Alfalfa Blotch Leafminer (Diptera: Agromyzidae), And Selected Parasites (Hymenoptera: Eulophidae) In Minnesota And Wisconsin, Usa, W. D. Hutchison, P. K. O'Rourke, D. W. Bartels, E. C. Burkness, J. C. Luhman, J. Heard

The Great Lakes Entomologist

Alfalfa blotch leafminer, Agromyza frontella, has been a serious pest of alfalfa, Medicago sativa, in the northeastern U.S. and in eastern Ontario, Canada. Until recently, the western edge of the A. frontella distribution in the U.S. was limited to eastern Ohio. We document for the first time, the occurrence of A. frontella in Minnesota and Wisconsin. Alfalfa stems damaged by A. frontella, based on adult feeding punctures, obvious blotched leafmining or the presence of larvae, were first found in 3 northern Minnesota coun­ties during October, 1994. Infested counties included Lake of the Woods, Cook and Lake, all …

Unusual Sex Allocation In A Solitary Parasitoid Wasp, Sphaeropthalma Pensylvanica (Hymenoptera: Mutillidae), Robert W. Matthews

The Great Lakes Entomologist

Sphaeropthalma pensyluanica reared from cocoons of the organ pipe mud dauber, Trypoxylon politum from Georgia over several years yielded only adult males. Possible explanations for this sex-biased emergence from this host are (1) obligatory heteronomous heterotrophy, in which the two sexes develop on entirely different hosts; (2) differential mortality in the immature stage, with female larvae dying during development; and (3) facultative size- dependent sex allocation, with female eggs laid only on hosts smaller than T. politum.

Sex-Related Color Patterns In Elytral Vittae Of Diabrotica Virgifera Virgifera (Coleoptera: Chrysomelidae), Louis S. Hesler, Leslie Hammack

The Great Lakes Entomologist

We evaluated the color patterns of elytral vittae by sex in adults of Diabrotica virgifera virgifera leConte. Our study examined >1000 beetles taken from a field population, a laboratory colony, and a reference collection containing 712 specimens from 15 of the United States and from the province of Ontario, Canada. The humeral and sutural vittae of each beetle's elytra were classified as being separate, partially confluent, or totally confluent with each other. The distribution of these elytral patterns was not independent of sex. Males tended to have confluent or partially confluent vittae, whereas females largely had separate vittae. Nonetheless, all …

Chemiluminescent Tags For Tracking Insect Movement In Darkness: Application To Moth Photo-Orientation, Joseph L. Spencer, Lawrence J. Gewax, James E. Keller, James R. Miller

The Great Lakes Entomologist

The flight tracks of Manduca sexta (Lepidoptera: Sphingidae) flying toward a 5 watt incandescent light bulb were recorded under low light conditions with the aid of a camera-mounted photomultiplier and a glowing marker technique. Small felt pads bearing a chemiluminescent (glowi ma­erial, Cyalume®, were affixed to the abdomens of free-flying moths. insects orienting to a dim incandescent bulb were easily visible to the naked eye and were clearly captured on videotape. On their initial approach to the light source, M. sexta were found to orient at a mean angle of -0.220 ± 2.70 (mean ± SEM). The speed of the …

Habitat Associations Of Sympatric Violet-Feeding Fritillaries (Euptoieta, Speyeria, Boloria) (Lepidoptera: Nymphalidae) In Tallgrass Prairie, Ann B. Swengel

The Great Lakes Entomologist

At 106 tallgrass prairies in the midwestern USA, 18,055 individuals of six fritillary species (Lepidoptera: Nymphalidae) were counted in 552.9 hr and 987.1 kill of transect survey effort from 14 June to 13 September during 1988-96. The relative abundance of Euptoieta claudia, Speyena cybele, S. aphrodite, S. idalia, Boloria selene, and B. bellona was analyzed for significant patterns relative to five habitat factors. Topographic diversity (i.e., whether the site was uniform or contained both uplands and lowlands) produced the most significant effects. Prairie patch size and vegetation type (wet, mesic, dry) also produced numerous significant patterns. When management type was …

Resistance Of Scotch Pine Varieties To Zimmerman Pine Moth (Lepidoptera: Pyralidae) And Its Impact On Sales In A Choose And Cut Christmas Tree Plantation, Clifford S. Sadof

The Great Lakes Entomologist

Nine varieties of Scotch pine, Pinus sylvestris, were assessed for their susceptibility to Zimmerman pine moth, Dioryctria zimmermani, in a choose and cut Christmas tree plantation. Trees were examined for wounds to estimate their susceptibility to this pest 7 years after planting in the field. Numbers of trees remaining after seasonal sales in years 7 and 8 were used to estimate marketability of each variety. Infestation rates varied significantly among varieties (11-75%). After sales, proportions of trees remaining also varied significantly among varieties (7-52%). Although Belgian trees were the most moth resistant, they were the least purchased by the …

Epizootiology Of The Fungal Pathogen, Zoophthora Phytonomi (Zygomycetes: Entomophthorales) In Field Populations Of Alfalfa Weevil (Coleoptera: Curculionidae) Larvae In Illinois, Marilyn J. Morris, Stephen J. Roberts, Joseph V. Maddox, Edward J. Armbrust

The Great Lakes Entomologist

The influence of the fungal pathogen, Zoophthora phytonomi, on larvae of the alfalfa weevil, Hypera postica, was studied in three alfalfa fields in Illinois. Disease epizootics occurred in all three fields and disease onset was ob- served within a fairly narrow range of degree day accumulations. At the height of each epizootic, percentages of infected larvae were between 80 and 100%, and the fungus contributed to the collapse of the weevil population in each field. Percent parasitism by the larval parasitoids, Bathyplectes cur­culionis and B. anurus, was lower in our fields than is common in mid-season alfalfa …

Effects Of Hybrid Poplar (Salicaceae) Clone And Phenology On Gypsy Moth (Lepidoptera: Lymantriidae) Performance In Wisconsin, James J. Kruse, Kenneth F. Raffa

The Great Lakes Entomologist

Gypsy moth (Lymantria dispar) developmental interactions with two hybrid Populus species clones were studied in laboratory trials. Significant differences in larval performance were found between clones and within the same clone at different phenological states. No larvae were able to complete development on clone NM6. All gypsy moth larvae feeding on clone NC5271 survived when leafflush was synchronized with gypsy moth eclosion in early May. However, neonates feeding on NC5271 foliage in July experienced in- creased mortality. Weights of surviving gypsy moth larvae feeding on NC5271 foliage in May versus July were not significantly different.

Factors Affecting Abundance Of Adult Karner Blues (Lycaeides Melissa Samuelis) (Lepidoptera: Lycaenidae) In Wisconsin Surveys 1987-95, Ann B. Swengel, Scott R. Swengel

The Great Lakes Entomologist

At 141 pine-oak barrens in central and northwestern Wisconsin, 3,702 Karner blues (Lycaeides melissa samuelis Nabokov) were found in 81.1 hr of transect surveys during spring and 6,094 individuals in 116.6 hr during sum­mer. Adults offive other closely related lycaenids occurred with Karner blues. The percentage of Karner blue males (of sexed individuals) correlated nega- tively with advancing date within brood, exceeded 50% on peak date within brood, but showed wide variability on a given date. Karner blues occasionally occurred up to 800 m from the nearest larval host, or in tiny, isolated host stands. However, all individuals were …

Natural Enemies Of Cranberry Fruitworm, Acrobasis Vaccinii, (Lepidoptera: Pyraudae) In Michigan Highbush Blueberries, Dogulas A. Murray, Robert D. Kriegel, James W. Johnson, Angus J. Howitt

The Great Lakes Entomologist

A two-year study was conducted in Michigan highbush blueberries to determine the complex of parasitoids attacking cranberry fruitworm, Acrobasis vaccinii. Eight parasitoid species and one fungal pathogen were collected. Parasitism of collected hosts ranged from 6.6% to 28.1%. The more common larval parasitoid encountered was Campoletis patsuiketorum (Hymenoptera: Ichneumonidae). The more common parasitoid recovered from fruitworm hibernacula was Villa lateralis (Diptera: Bombyliidae). This study documented six unreported natural enemies of cranberry fruitworm, including C. patsuiketorum; V. lateralis; Diadegma compressum (Hymenoptera: Ichneumonidae); Compsilura concinnata (Diptera: Tachinidae); Memorilla pyste (Diptera: Tachinidae); an undescribed Microtypus species (Hymenoptera: Braconidae); and a fungal pathogen, …

Oviposition By The Banded Sunflower Moth, Cochylis Hospes (Lepidoptera: Cochylidae) In Response To Helianthus Annuus Pollen, John F. Barker, Sharon Grugel

The Great Lakes Entomologist

Oviposition on an artificial substrate by the banded sunflower moth Cochylis hospes Walsingham was examined in response to sunflower pollen (Helianthus annuus) and sunflower pollen extract. Sunflower pollen in quantities as small as 0.2 mg significantly reduced oviposition on an artificial substrate relative to a control without pollen. Aqueous pollen extract applied to the artificial substrate significantly reduced oviposition with respect to the control substrate that was treated with solvent. Banded sunflower moths have gained some reproductive or competitive advantage by ovipositing on the bracts of sunflower and a deterrent effect of pollen could, at least in part, have had …
